Fiber loss can be also called fiber optic attenuation or attenuation loss, which measures the amount of light loss between input and output. Factors causing fiber loss are various, such as intrinsic material absorption, bending, connector loss, etc. 3 recommends a maximum value of 0. ) (This does not include the connectors that plug into the end equipment. This value should be determined by the system designer. Fiber optic loss is one of the most fundamental parameters in optical network engineering, yet it is often misunderstood as a purely theoretical value used only during design calculations. In real-world deployments, fiber optic loss directly constrains transmission distance, split ratio, network. A loss budget is the calculated loss of the cable plant while a power budget is the optical loss tolerable to a communications system. This is primarily caused by light absorption.
